On-site, Telephone and Video Interpreting
Interpreting services can be delivered in multiple modalities. The most common modality through which interpreting services are provided is on-site interpreting. On-site interpreting Also called "in-person interpreting," this delivery method requires the interpreter to be physically present in order for the interpretation to take place. In on-site interpreting settings, all of the parties who wish to speak to one another are usually located in the same place. This is by far the most common modality used for most public and social service settings.
Telephone interpreting Also referred to as "over-the-phone interpreting," "telephonic interpreting," and "tele-interpreting," telephone interpreting enables the interpreter to deliver interpretation via telephone. The interpreter is added to a conference call. Telephone interpreting may be used in place of on-site interpreting in some cases, especially when no on-site interpreter is readily available at the location where services are needed. However, telephone interpreting is more commonly used for situations in which all parties who wish to communicate are already speaking to one another via telephone (e.g. applications for insurance or credit cards that are taken over the phone, inquiries from consumers to businesses that take place via telephone, etc.)
Video interpreting With video interpreting, interpreters work remotely with a video camera and audio feed, so that the interpreter can hear and see the other parties, and vice versa. Much like telephone interpreting, video interpreting can be used for situations in which no on-site interpreters are available. However, video interpreting cannot be used for situations in which all parties are speaking via telephone only. Video interpreting requires all parties to have the necessary equipment. Some equipment enables interpreters to control the camera, in order to zoom in and out and to move the camera toward the parties that are speaking.
